Expiration Day is William Campbell Powell's debut YA novel, and it's an exciting start. The novel is set in a world in which human fertility has collapsed, taking the birth-rate virtually to zero, sparking riots and even a limited nuclear war as the human race realizes that it may be in its last days. Order is restored, but at the price of basic civil liberties. There's a little bit of Orwell (a heavily surveilled and censored Internet); but mostly, it's all about the Huxley. The major locus of control is a line of robotic children -- all but indistinguishable from flesh-and-bloods, even to themselves -- who are sold to desperate couples as surrogates for the children they can't have, calming the existential panic and creating a surface veneer of normalcy.
Expiration Day takes the form of a private diary of Tania, an 11 year old vicar's daughter in a small village outside of London. Tania's father's parishioners have found religion, searching for meaning in their dying world. He is counsellor and father-figure to them, though the family is still relatively poor. Tania is a young girl growing up in the midst of a new, catastrophic normal, the only normal she's ever known, and she's happy enough in it. But them she discovers that she, too, is a robot, and has to come to grips with the fact that her "parents" have been lying to her all her life. What's more, the fact that she's a robot means that she won't live past 18: all robots are property of a private corporation, and are merely leased to their "parents," and are recalled around their 18th birthday, turned into scrap.
